MACHINE N. Y., assignor, by mesne assignments, to Crown Cork 8: Seal Company,

My invention relates to filling machines and particularly to filling machines of the semi-automatic type that may be either manually or automatically controlled during the cycle of operation thereof.

An object of my invention is to provide a filling machine that is simple and relatively inexpensive and the operation of which during a filling cycle may be initiated manually and completed automatically.

A further object of my invention is to provide a filling machine the operation of which in its cycle may be initiated manually and which, if not interrupted by the operator, will stop and r start automatically until its cycle is completed.

A further object of my invention is to provide a control system for filling machines that is entirely automatic to complete the cycle thereof but which may be operated manually at any portion of the cycle to substantially instantly stop the machine.

A further object of my invention is to provide a fluid-pressure system for controlling the operation of filling machines that is substantially instantly operable to effect the operation of the machine or to bring it to rest and retain it in such condition until the control system is again operated to start the machine.

A further object of my invention is to provide fluid-pressure controlled means for actuating a filling machine and a fluid-pressure controlled brake therefor that are so arranged that one is operative While the other is inoperative. I

A still further object of my invention is to provide means whereby the supply of liquid to a container is automatically controlled in accordance with the position of the container and the degree to which the latter is filled.

The filling machine of my invention is provided for the purpose of supplying a demand for a relatively simple and inexpensive machine that may be operated partially by manual means and partially by automatic means. In general, the machine, which is provided with a single filling head that is stationary, begins its filling cycle automatically when a bottle is placed in position on the machine. The machine then automatically completes its cycle, stopping and starting at appropriate points in the cycle until 0 the bottle is filled and the usual crown is applied thereto.

The bottles are fed to the syruping position by any suitable mechanical means but are moved from the syruping position to the filling position manually. A lever actuated by the bottle initicorporation of New York 1930, Serial No. 418,675

ates the operation of the machine and when the filling cycle is completed the bottle is removed manually and another bottle placed in position, whereupon the cycle is repeated.

The automatic means for controlling the operation of the machine comprises a fluid-pressure control system, including a fluid-pressure clutch for connecting and disconnecting a constantly-driven motor to the machine. This clutch is controlled in accordance with the progress or" the machine in its cycle and stops or starts the machine at appropriate points in the cycle. Each cycle, however, must be initiated by the operator.

The machine is retained in its stationary position by a friction brake that is fluid-pressure controlled and a single valve operates to simultaneously release the brake and apply the clutch, or to release the clutch and permit a spring to apply the brake to quickly bring the machine to rest and to hold it stationary until the valve is again operated.

The supply of liquid to the bottle to be filled is controlled automatically by the descent of a crowning head to seal the bottle in the filling head and to seal the interior of the filling head and the crowning head from the atmosphere. The supply is cut off when the crowning head is slightly raised to permit the bottle to be lifted to crowning position. This movement occurs automatically upon the filling of the bottle to a predetermined degree.

The details of my invention will be described in connection with the accompanying drawings, in which Figure 1 is a view in front elevation of a filling machine constructed in accordance with my invention;

Referring particularly to Figs. 1 and 2, the filling machine illustrated therein comprises a base or pedestal l, on which is mounted a framework 2, through the central portion of which extends a vertical rotatable shaft 3. The lower portion of the shaft 3 is provided with a grooved cam 4 and with bottle height-compensating mechanism (not shown), such as that shown and described in my Patent No. 1,668,264, dated May 1, 1928, whereby the relative position of a bottle lift 5 may be adjusted with respect to the coacting parts of the filling machine in accordance with variations in height of the various bottles to be filled.

The upper portion of the shaft 3 is provided with a similar grooved cam 6, shown in Fig. 3 and in dotted lines in Fig. 2, for operating the filling and crowning mechanism as will be hereinafter described. The shaft 3 is also provided with a bevel gear *7, which co-operates with a similar gear 8 to drive the mechanism of a crown hopper 9.

A stationary filling head 10 coacts with a ver tically movable crowning head 11 that is controlled by the cam 6. A liquid supply chamber 12 is communicably connected to the filling head 10 and an air-retreat chamber 13 is similarly connected to the crowning head 11.

Referring to Figs. 3 and 4, the filling head 10 comprises an annular member 14 for enclosing and supporting a rubber gasket 15 for making sealing engagement with the necks of bottles being filled.

The crowning head 11 comprises a hollow cylinder 16 that is connected to a vertically slidable member 1'? carrying a cam roller 18 for coacting with the groove 19 of cam 6. A coil spring 20 extends between a flange 21 on the cylinder 16 and a sealing sleeve 22 at the bottom of the latter. A flanged sleeve 23, which is slidable within the sleeve 22, is connected to the cylinder 16 at its upper and at its lower end to a sleeve 24.

The sleeve 24 has a slot 25 for admitting a crown when in its upper position as shown in Fig. 3. The sleeve 24 in its lower position compresses the gasket or throat rubber 15. This sleeve also contains the crowning die (not shown) and has the usual pawls (not shown) for yieldingly retaining the crown in position during the filling operation.

A plunger 27, which is slidable in the sleeve 23, is pressed downwardly by a spring 28 and operates to remove a filled bottle after the crown has been placed thereon and the bottle has been released by the gasket 15. The plunger 2'? is provided with a cam 29 above the head 11 which, when actuated upwardly, turns an arm 30 connected to a rod 31.

The latter has at its lower end a second arm 32 which is thus turned to a position in alinement with the stem 33 of a valve 34 for controlling a passageway 35 from the supply chamber 12 to the filling head 10. A spring 36 normally maintains the valve 34 closed. The rod 31 is spring-pressed toward its inoperative position.

The air-retreat chamber 13 has a differential piston 36a therein, the lower side of which is Of greater cross-sectional area than the upper side, whereby, when equal unit pressures are applied to opposite sides of the piston, the latter moves upwardly. The top of the chamber 13 is connected to the supply chamber 12 by a flexible hose 3'7. The piston stem 38, which extends through the top of the chamber 13, is provided with a screw-threaded extension 39 that may be adjusted to coast with a lever 40 pivoted to the frame work of the machine. The volume of liquid which is required to fill a bottle is controlled by the adjustment of the extension 39 in relation to the lever 46 as hereinafter described.

A syruping head 41 is provided adjacent to the filling head whereby bottles that have been provided with a supply of syrup may be easily and conveniently moved from beneath the syruping head to the filling position under the filling head. The syruping head 41, which is preferably of the automatic type, is operatively connected by a rod 42 to a cam 43 carried by the shaft 3 where by the head automatically descends during each filling cycle to supply the bottle in registry therewith with a predetermined amount of syrup.

Bottles may be actuated to the syruping position by a rotatable disc 44, which carries the bottles successively against a limit stop and retains them in that position by friction between the stationary bottle and the rotating disc. Any suitable mechanical means may be employed to supply bottles to the rotating disc 44 or they may be placed thereon manually.

Crowns from the hopper 9 are automatically supplied to a crown chute 45, which, in turn, supplies one for each filling operation through the slot 25 in the side of the movable sleeve 24.

The shaft 3 and its connected driven parts are operated by means of a motor 47, which may be, for example, an electric motor and that is connected by a pinion 48 to a gear 49 for driving one member of a fluid-pressure controlled clutch 50.

As shown in Fig. 11, the clutch 50 comprises a cylindrical casing 51, connected to the gear 49, and within which a diaphragm 52 of rubber or other suitable material is caused to tightly engage the slightly conical clutch member 53 that is rigidly connected to a horizontal. shaft 54, the latter being connected by suitable gear mecha nism 54a to the vertical shaft 3.

At the opposite end of the shaft 54 is a hand wheel 55, by means of which the mechanism of the filling machine may be actuated when Adjacent to the hand wheel 55 is a friction brake 56, which coacts with the shaft 54 to stop the v mechanism and to hold it stationary.

A fluid-pressure system for operating controlling the filling machine comprises a compressor 58 that is driven by the motor 47 by means of suitable gearing 58a. connected through a pipe 59 to a valve mechanism 60 which controls the application of fluid pressure to the clutch 50 the brake 56.

Reference may now be had to Figs. 5, 6, '7 and 8, in which the details of the mechanism for controlling the fluid-pressure control system are shown in enlarged detail. The valve mechanism 60 comprises a stationary casting 61 having a tubular sleeve 62 that is provided with an inlet The compressor 58 is opening 63, an outlet opening 64 and exhaust connect the pipe 69 through the exhaust ports and 66 to the atmosphere to relieve the clutch and the brake of fluid pressure.

The valve piston 67 is actuated to the one or the other of the positions just described by means of a vertical rod 71 that is slidably mounted in the casting 61 and is arranged to be held by friction in either its upper or its lower position. It is provided with two horizontally-extending arms '72 for engaging the respective ends of the piston 67. The position of the rod 71 is controlled in part by a bell-crank lever 73 that is adjacent to the bottle lift 5 and has an upper arm '74 that is engaged by a pivotally-mounted bracket '75 when a bottle '76 is placed in filling position on the bottle lift 5.

The bell-crank lever 73 has a lower arm '77 for engaging a lug 78 secured to the shaft '71. The operation of the bracket '77 and the bellcrank lever '73 actuates the rod '71 downwardly and the piston 67 is in the position in which it is illustrated in Fig. 5 to apply fluid pressure to the clutch 50 and the brake 56.

The upper end of the rod 71 is provided with a horizontally-extending member 80 that is provided with a vertical pin 81 for coacting with cams 82 and 83 that are unsymmetrically mounted on a cam ring 84 that is carried by the shaft 3.

The rod 71 is also provided with a lug 85 that is adapted to be engaged by the lever 40 when the outer end of the latter is actuated upwardly by the screw-threaded member 39 of the airretreat chamber 13.

It will be noted that the driving member, the shaft of the motor 4'7 and including the gear 48, is connected with the driven member, the shaft 3, by connections 54a, and that these connections include therein the clutch mechanism 50, so that the actuation of the driven member 3 and the various mechanisms carried or controlled thereby is determined by the setting or the release of the clutch 50. The setting of this clutch, to ensure the application of power to the driven member, results from the proper positioning of a bottle upon its support 5, while the release of the clutch, to interrupt the application of power to said shaft, results from the movement of the cams 82 and 83 carried by the shaft 3.

The operation of the mechanism illustrated in Figs. 5, 6, 7 and 8 will be readily understood from the foregoing. The placing of bottle in position on the bottle lift 5 will cause the rod '71 to be drawn downwardly to apply compressed air to the clutch 50 and brake 56. The rod will be actuated upwardly when either of the earns 82 or 83 engage the pin 81 and the machine will accordingly be stopped. The machine will also be started when the rod '71 is actuated downwardly by the lever 10. The rod may also be ac tuated manually in either direction to start or stop the machine, as the case may be.

The details of the brake mechanism are illustrated in Figs. 9, 10 and 11. The shaft 54 is substantially surrounded by two pivotally-connected semi-circular bands 86 and 87 that are provided with the usual friction material 88. Normally the brake bands 86 and 87 are retained in engagement with a collar 89 by a spring 90 which bears against the outer side of the band 86 and tends to draw a bolt 91 in the opposite direction to clamp the bands 86 and 87 tightly against the collar 89. The brake is released when fluid pressure is applied through a pipe 92, causing a piston 93 to engage the end of an adjustable stud bolt 94 for separating the brake bands 86 and 87 against the force of the spring 90.

The connections of the fluid-pressure control system are shown in Fig. 11. It will be noted that the compressor 58 is connected by the pipe 59 to the inlet side of the valve mechanism 60, the pipe 69 on the outlet side of the valve mechanism being connected to both the clutch 50 and the friction brake 56. It will be readily understood, from the foregoing, that the application of fluid pressure to the clutch and to the brake causes the former to be operative to rotate the shaft 54 and to simultaneously cause the brake to release the shaft 54 to permit the latter to rotate freely. Upon the actuation of the valve mechanism 60 to out off the supply of fluid pressure from the pipe 59 and to permit the exhaust of the compressed air from the clutch 50 and the brake 56, the former is released and the brake is engaged simultaneously to quickly stop the shaft 54 and to retain the latter and its connected parts stationary until fluid pressure is again applied.

In the operation of the filling machine, it may be assumed that a bottle has been previously placed under the syruping head 41 and that it is ready to be filled. The bottle '76 is actuated into position against the bracket and the latter operates the bell-crank lever '73 to depress the rod '71 to start the machine in the manner previously described. During the initial portion of the rotation, the bottle is lifted by the bottle lift 5 and the crowning head is lowered by the cam 6. The bottle is inserted in the filling head 10 and it engages the crown previously inserted and presses the cap and the plunger 2'? upwardly to lift the cam 29 carried thereby.

The arm 30 turns the rod 31 and the arm 32 and these parts remain in this position to actuate the valve 34 since the crown is held by suitable pawls (not shown). The height of the bottle is compensated by the limitation of the upward movement of the bottle and the bottle lift 5 is lowered to place the bottle mouth in the gasket 15.

The slidable member 17 then descends to depress the crowning head 11 which makes a sealing engagement with the filling head 10 and compresses the gasket 15 around the neck of the bottle. The last portion of this downward movement of the head 11 causes the valve 34 to open and the bottle is supplied with liquid under pressure from the supply chamber 12. During this portion of the operation, the cam ring 84 has travelled through an are represented by thelonger distance between the cams 82 and 83, the cam 83 engaging the pin 81 at substantially theinstant that the bottle is in condition for filling, as previously de scribed. The machine is brought to rest by the upward movement of the rod 71 and the bottle .76 is filled in the usual manner by the supply of liquid under pressure thereto, the machine remaining stationary during this portion of the operation.

When the screw-threaded member 39 is elevated by the diiferential pressure within the airretreat chamber 13 to engage the lever 40, the latter depresses the rod '71 and the machine again operates as the bottle is filled to the desired degree. The initial movement of the machine causes the cam 6 to raise the slidable member 17 to lift the crowning head 11 slightly to permit the closing of the valve 34 to cut off the liquid supply. This slight upward movement also releases the gasket 15 sufficiently to permit the bottle to be raised by the bottle lift 5 without breaking the seal and without damage to the gasket.

The raising of the bottle into the crowning head causes the crown to be affixed in the usual manner. The cam 6 then lifts the crowning head 11 to release the gasket 15 and the bottle lift lowers the filled bottle to its initial level ready for removal. At the completion of this operation, the pin 81 is engaged by the cam 82 and the machine is again brought to rest at the end of the filling cycle, with the bottle filled and crowned and ready for removal. The filled bottle is removed manually and a second bottle moved from the syruping position to the filling position in the manner previously described, whereupon the filling cycle is repeated.

The supply tank is filled from the usual carbonator which maintains pressure on the liquid in the supply chamber during the time the machine is in service.

When pressure is released in the filling and the crowning heads by the lifting of the latter at the completion of a filling cycle, the pressure on the upper side of the piston of the air retreat chamber causes the piston to return to its lower position in readiness for the succeeding filling operation.

The provision of the single control device for the clutch and the brake insures their simultaneous operation and quick starting and stopping of the machine.

The pneumatic control system that may be operated manually either to start or stop the machine places it entirely under the control of the operator whenever desired. The automatic operation of the control system from a number of points renders the machine responsive to all essential operating conditions.

The arrangement whereby the liquid supply is connected or disconnected from the filling head by a relatively slight movement of the crowning head at one extremity of its path' of movement to fully compress or slightly release the gasket without materially affecting its sealing engagement affords a simple and efficient means for controlling the liquid supply at appropriate points in the filling cycle. Also, the slight relaxation of the gasket or throat rubber permits the bottle to be raised through it for crowning without damage to the gasket.

The foregoing and other advantages will be apparent to those skilled in the art relating to filling machines. My invention is not to be limited to the preferred embodiment shown and described herein except as expressed in the appended claims.
